If I hadn't already bought the 100 sumthin dollar malossi primary gear kit I might have just took that off your hands but I'm sure with the power levels in going to be at 1 bearing would probably hold it lmao. I will have the old input shaft laying around if you need it for anything though.

Well it looks as though usps did me good and delivered the parts a little early so if they really did I'm going to test fit everything tonite for the trans and if all is right get the gears pressed on and off asap so I can just swap over the flywheel and stator brake hardware and intake friday/saturday and have my bike back up and running with a brand new dialed in engine this weekend. Hopefully in the near future I can get my exhaust situation figured out and have a pretty fast 50cc bike running around town.

The trans fits together now like a glove so all is well. Going to get the gears pressed on and off tomorrow if I can afford it if not i will Friday and have things up and running this weekend aslong as my luck holds up. I'm stoked because I'm at 16,000 miles now and its time to say the least. I'm sure I've got to be getting close to some sort of record for a stock bottom end lol.

What gear ratio are you shooting for? IMA have a 11:1 when the gears get here

I think it was a 10.something ratio when its all said and done. But I ran into a snag and the gear that needs to be pressed into the malossi gear is noticeably larger than the hole in the malossi one. The shop that was going to do it pointed it out to me. Ik it was supposed to be a tight fit but this is a little too tight so I'm not sure what I should do about that. They cost too much to just throw them out.

Well I'm solving my problem the right way this time lol. I got the old gear pressed off and I dropped the gears off at a machine shop to have the malossi gear machined out to the spec of the old gear. They are only going to try and charge me for a half hr so if it doesn't take that long they will press the secondary gear into the malossi gear for me as well. If not I have a place that will do it for me for free or under 10 bux so either way I'm happy with that.
If anybody needs machining or pressing done in the Tampa fl area look up anchor machining on the corner of 7th and 39th street they are good people and work with their customers unlike corporate businesses.

Sorry for the delay on updates. I started a new job that's basically 7 days a week and 10-12 hour shifts so I've been way too tired to do much but I got cracking the last 2 days and it didn't go too well.
The shop pressed the gear on a hair too far but I got that pushed back out to where it belongs and installed had the top end buttoned up and was installing the flywheel and realized it wasn't catching and pressing on as soon as the old crank. Turns out the taper is smaller on that side of the crank so either I need a diff crank or a new flywheel that has a small taper and not the larger one my bike has. My boss man has a stuffer crank from motoforce so if it has the right taper I may use that for now until I can get that sorted out. I put the old motor back in for the time being with the ports raised a little bit to help with the power up top. The old motor is pulling a little better up top and I've managed to hit 55 with the little 50cc top end.
I'm wondering though what may have caused my rpms to drop on acceleration with the over range. I'm going to use lighter weights if I have a set for now or a stiffer contra spring. The clutch adjusts at a much higher speed now and it drops to almost 7000 rpms when it hits 50 so it takes it back below my powerband for the cylinder or exhaust. Once I get the cvt dialed in i think these gears are going to be perfect for my uses. I'll be able to pull them to 55 without a problem and not be at 10,000 rpm to do that speed.

Took it out today with the malossi red contra spring in and still the 7g sliders and 1500 rpm clutch springs. It turns out I don't have lighter weights around for the over range just 7g rollers and 10g sliders.
Take off rpm is 8000-8200 rpms and it drops down to about 7000 rpms at 30 and stays there till 40. 45mph is at 7500 rpm and 50-55 is 7800-8200 rpms. 60 is really close to the same rpms I think it was 8600 rpm getting there then when the over range settles it was about 8100. It took a while to get to 60 but it got there. When I have the new engine useable I'm sure it will get to 60 or more alot easier.
55 isn't hard to get to with the gears surprisingly enough it does it much quicker than with the stock gears. Plus it has a sweet gear whine and in really happy about that. Most people and companies say their noisier due to the straight cut and it sounds like a supercharger once you hit 16mph and stays loud until 45 before exhaust and road noise is louder. It gets some good looks when it takes off at 16 and whines like it started making boost.

Well I'm going to ditch the top trophy cylinder sadly enough. I seen a stupid good deal on a malossi mhr 50cc and i bought it. Thanks to my new job I can mess around with more things and still take care of bills. This bike wont be my daily driver for long as im in the process of buying a truck so why not have a little more fun? I should be able to pull all of the gears I have with that top end no questions asked so if all goes well ill have the fastest 50cc bike on the block within a week.

Alright I've thought about it for a little bit and i think I can let it go to ya. If your willing to do 30 bux and either another 5 to split the shipping or maybe 10 because it might be 10-15 the last cylinder cost about that much to ship out. I think we could both walk away happy at that price. I'll even throw in my 10mm pin and 12mm pin piston to go with it so either way you have a piston to use. Maybe buy some new rings when you get it for good measure. I have about 2000 miles or so on it so you'll be pretty set for a while with that. The head and what's left of the squish band go with it along with some stickers I believe. Anything else the kit has left goes aswell. I'll check my inventory when I get home and let you know what I have.

Haven't been on here in a while so I figured id update for you guys. Have been dealing with an abscessed tooth the last few days but its finally improving so I'm a little more lively outside of work. I received the malossi mhr 50cc kit and detuned the crap out of it. I ended up using the cylinder base spacer from the top trophy kit so the compression wouldn't be 15.8:1. It turns out thats only the case with the 85mm conrod and I'm using a stock 80mm one and its not full circle and this kit needs one to perform properly.
I also used a metal head gasket and the squish band ontop of it and was fine running 89 octane pump gas but it was pretty lacking after 50. I took out the metal head gasket but left the base spacer in and boy did it wake up. I have it jetted at about 85 main jet if I remember right and the needle is in the middle and its a hair rich.
Currently its compression is pretty good it hurts to have your finger in the plug hole and spin it wth your hand but squish is around 1.13-1.35mm and it calls for .5mm or so. I figure it I take the spacer out its going to make alot of power nut still be good with pump gas. I'm still running 89 octane and I'm pretty sure I could use 87 if I really wanted to. With the cylinder base spacer out I think premium would suffice but it would have a boat load more power and set squish around .7-.8 mm maybe .9mm.
Top speed I've hit now that its broken in is 60 mph and got to 55 really well. Within a 1/3 mile I can do 60 on flat ground with no major wind and way quicker I can get to 55. Even quicker than my Athena 70cc kit could get to 50.

Wow that sounds wild for a 50. Sorry about the tooth they can make you miserable. I've been really busy at work. Didn't realize you had your new kit already.
