ERR,dont think it really matters looking at the construction of the bearing as there are areas on both sides that are open to oiling..Main ball bearings dont need pressure oiling,just a drool here and there will keep them happy..The big end bearing on the con rod is where all the high stresses are and thats a whole different subject,so ride on and worry less!!  The 2 stroke master has spoken!!! |

I decided to do a sort of proof of concept ride yesterday. I wanted to ride at least 100 miles on roads more typical of the area. I know I rode 100 miles (+/- 30 miles) 3 different nights at car shows already, but that's all light to light, cruising 30-35MPH. I've also taken a lot of test rides and rode to a friend's house, but those were mostly 30 miles and under. I figured if it's fine for 30 miles, it's fine for 100, but I said from the start that you don't see people riding hyper race stuff on long rides so I wanted to do it... even though it's not full on hyper race at this point. Even if it never works to ride later with a different exhaust and ignition, I'd know how it stands as setup. I thought about the beach, my usual long ride. It was too late in the day for me to be gone that long, because I had other things to do and I know if I got there I'd take a few laps and end up hours later than planned. Decided to go to the swamp. I haven't taken T2 there for years. I go there somewhat often on the TMAX, but getting there on a small scoot involves being on a highway for a few miles and there's only one gas station that only carries 87 octane for many miles once you're in the swamps. I wanted to take my DSLR, which has a big case. It was too big to be comfortable to ride with just hanging from the handlebars. Ended up putting the case in a shopping bag and hanging it on the gas tank's filler neck. Felt secure, but seemed kinda iffy with highway speeds and a lot of turns ahead. Actually worked well though. I never really saw it moving around.  It was about 15-20 miles before I got on the highway for a few miles. I had a headwind, but I could still keep up with traffic. Then I stopped to get gas. I knew that one route that I wanted to take was about 70 miles long. I knew that I got 40MPG around the beach, but I wasn't sure if it would do that well on open roads. Normally my scoots experience the reverse of what you see in most vehicles with city vs highway MPG, and I'll do better in the city with slower stop and go. I figured if it got 40MPG still, I was good to go on the 70 mile route with about a 100 miles range with my 2.5 gallon tank. If it got something like 30MPG, then I was going to shorten the route, because that would only be about 75 miles if I could use all of the fuel in the tank. To my surprise, it did better than 40MPG. I got 47MPG with a lot of 40-50MPH cruising, about 3 miles of highway, and then a quick ride through a town. Original route it is! I encountered a lot of water in the road in one section of the swamps. As much as I recall seeing there, but I tend to avoid it when tides are known to be really high and I know it can get much worse. Nothing too deep, but enough to splash my shoes and feet even at 6-8MPH. Also enough to get water in my rear GoPro housing. I use an open back on it to let sound in, but with it aligned on center with the tire since my rear re-do, it gets water thrown at it. Used to be off to the side and it wasn't an issue. Anyway, I went to change the battery in it later and the button to record wouldn't work. Then when I got home the camera wouldn't turn on at all. It's in a bowl of rice ATM, so fingers crossed. The swamp has many more turns than anywhere else near me. That combined with the lack of traffic and speed traps is a lot of why I go there so much on the TMAX. T2 does OK but it doesn't handle like the TMAX... in the turns or on the straights. Still fun though. Beats riding a bunch of long straight roads and the scenery is great.       When I made it back to a gas station, I had gone 69 miles and I averaged 47MPG again. I was pretty impressed with that. Not what I expected with the huge ports in this cylinder. School was out as I rode through town again before heading home. 2 kids on bikes pointed and I think they yelled for me to do a wheelie. I was doing 25MPH though. Then someone older was walking into his house, heard the 2T, and turned around with his hands in the air working an imaginary throttle. I seem to get more of that since the LC stuff and especially now with the bright wheels. It's normal at car shows (they do it to rental scooters), but now I get it just going through towns. I was doing 65+ at times on the way home. It feels like it's coming apart at that speed and over 11,000RPM. I have never balanced these wheels/tires so that is prob part of it. Some of it may be the engine or gearbox as well. It's "interesting" being on the highway doing 65 in traffic with all kinds of vibration. Combine that with having experienced many belt failures and I was imagining the belt snapping and locking the tire if front of cars. Good times. lol I've got Ride-On (thick goo tire balance and sealing aid) here and I think it's about time that I use it. I made it home though and all totaled it was 118.8 miles. Not a super long trip, but long enough to show me that this setup indeed works for cruising if needed. I'm still amazed that I got about 2-5MPG better on this than the TMAX. I've become accustomed to 30MPG from the 103, seeing as low as the high 20MPG range, so this is nearly 20MPG better. Then again, this doesn't seem to be perpetually leaking coolant or pressure, so that's gotta help some. I'd imagine the stuff that makes it's more race friendly like 1 ring and a smaller lighter piston can't hurt. I think prob the real downfall of this setup is that most likely it's not going to last a long time. That's my understanding of it anyway. We'll find out eventually if I don't fry it some other way first. I gave it a quick wash as soon as I got home. Hopefully the salty water won't cause much harm that way. |

Great ride! If I ever make it up there I want to ride that route. That scenery is the kind of stuff I love.
65+ at over 11K, is this the fastest setup T2 has ever had? It will be interesting to see how long this build lasts. It could be possible your slightly restricted hyper race will have a long life. You mentioned you were going to make it full hyper race at some point. What is needed to get there, a shiney pipe and a better iggy?

Sounds like you've achieved your desired result, just a question of longevity now. Congrats!

65+ at over 11K, is this the fastest setup T2 has ever had? It was a little faster with my first 103. That was ported to ~200 exhaust and would over rev to 12,000RPM before the OR CVT. Combined with the stock 10.1:1 gears, it managed over 70MPH. I haven't had any other big engine do that, and even that one wouldn't do it once it had an OR kit. Seemed like I got lucky with just the right combo that time. This and the 100s have all been really close though. The willingness to run at higher RPM certainly helps this engine with speed vs my typical 103s. It will be interesting to see how long this build lasts. It could be possible your slightly restricted hyper race will have a long life. You mentioned you were going to make it full hyper race at some point. What is needed to get there, a shiney pipe and a better iggy? High RPM exhaust and lightweight ignition. Those are definite needs. Some YouTube comments say just the exhaust. Actually a lot. They weren't watching all parts though. When I was tuning and it revved around 12,000RPM there was a lot of vibration. Hopefully just the flywheel. No way am I even considering a high rev exhaust till it has a racing ignition. Could be that my lightening job sucks, but I wouldn't want to rev like it will need to regularly with a stock flywheel. Plus, it should be a big advantage to get rid of lag created by flywheel mass when you're trying to reach for the sky to get moving. I also get comments about needing a huge carb. I'd think my 25mm would work since most recommendations from sites and manufacturers of this stuff are 24-28mm. What's funny is that I got all these comments about a pipe and being slow. Then I posted the video of it's speed on flat ground, 67 GPS. Then I get a couple saying, it will do 70 or 70+ with a pipe. lol If it doesn't gain at least 3MPH with 3,000RPM, I may actually beat the hyper race exhaust with a hammer out of principle. I think if I cared enough, I could get a couple more MPH out of it now. Honestly, it starts to get into "bragging rights" at that point. I am curious to see what it will do on the top end, but mostly I want to see how quick it can get moving from a stop. I really enjoy surprising all of the people that think scooters are nothing more than slow road-blocking nuisances that can't get out of their own way at traffic lights. |

You gonna try a fancy iggy with your existing "hyper pipe"? You may not need a shiney hyper pipe after all!

I thought it was the U pipe that makes all the power...
I think it’s funny YouTube thinks you’ve got a stock pipe but can still manage 67.

65 Plus is awesome on these scoots .
And requires some Mad Tuning Skills .
Over on Zuma Forums we had guys talk about 60 mph and up builds but only a couple would provide GPS proof.
It takes alot of extra Horsepower to over come the wind resistance of each extra 5 mph .

Both because I think it's a lot to change at once with the ignition and exhaust and because I want to see how it changes the current setup. |

I just had a comment this week from a fellow with a 30HP 170cc GY6 that goes 100MPH and 0-65MPH quicker than my TMAX. He has videos up, but you can't tell much. I told him I wish he were closer so I could see it riding with my TMAX first hand and he said the TMAX is a boat and starting talking about some 250 4T swap in place of a Gilera Runner engine. OK, I'm out.  |

You should just do a thread on YouTube comments. If I ever need a laugh it would cheer me up. 😁

A blanket reply to all those "armchair advisor's" is "How many pipes have you designed and built throughout your short lifetime?"  |

Some armchair advisors have many more miles and builds behind them than in front of them. You'll know the feeling when, and if, you get there.

Trying stiff pillow springs in the HiT clutch and video from the swamp test ride : www.youtube.com/watch?v=FdV6oxjZpMEAlso, I put the GoPro that got wet in a bowl of rice and it now works again! |
