Pipe length gets shorter as RPM's increase,belly gets bigger too..Both increase as engine size gets bigger.Your pipe could be small because its designed for a 50cc only,or the bean counters cut back on the sheet metal,,Leo Vince and Technigas are known for packing screens and baffles in the aft cone,that totally messes up a pipes ability to work properly,BUT its quieter!Lots of cheapy pipes have no reasonable design for power,just shiney and cheap with a nice sticker..If you could run down an old MRP pipe for a TGB,then you'd have something to build on..Gotta remember that port durations,port flow,squish,& iggy timing also play a big part in making power and all must be matched for a happy motor..

www.dkcycle.com/item-1497-mrp-tgb-pipe-mrp-exhaust-for-tgb-49cc-25981.htmlI searched up this. This site actually seems to have a lot more tgb performance parts than anywhere I've seen. I'm not sure if I'm looking at everything and reading it right. This tecnigas matches every detail of a next r on the site. And it's ridiculous quiet. I've questioned if it's packed with stuff, or if it's just a little pipe that would perform best on a fifty. Scrappy dogs has tgb pipe that looks beefy, but it's clearly stated "not for r50x". I wonder if it has to do with how it's hard to mount a pipe with the r50x swing arm. I could barely get this tecnigas on when the swing arm was still on it, the mounts definitely wouldn't match. I don't want to give up on this cylinder yet and pull the polini trigger, especially if my pipe is just going to hold me back, but the piston slap noise is awful loud. I wouldn't be surprised if it just slapped to pieces at some point.

Waay too much for the MRP pipe,,Scrappy pipe looks like a generic belly grafted to a long headpipe,,Technigas is likely better.The TGB has decent transfer tunnels,reed design is iffy,dont know the iggy setup/curve..If the technigas is the right exterior dimensions(likely not),then hacking it and gutting it would be the best solution..An $11 endoscope would tell you if its got garbage goodness lodged within.If you can post some pipe dimensions,I'll give you my opinion if its worth work or the trash can..

I would think a little more girth to this pipe would maybe help it. A lot of ladies could say the same  I'll order a scope tonight. I just feel like this is the bottom of the barrel pipe, but that may be biased due to being used to the size and great performance of the pipe on the Super 9. That bike has ruined me for sure. The reed block is an aftermarket polini work a small riser in it, the intake was super small going into the reeds, I opened that up, pictures earlier in this thread. The transfer tunnels, are you talking about from the case to the cylinder? Because I'm not too impressed with the transfer ports on this naraku kit. Let's see if this will upload here, pipe dimensions.   I'm about to try to get my port durations, I was half assing it last time. |

I got an mrp pipe on my keywest and it rips,way better the technigas r pipe got one of those too,been looking at a yasuni r or a gianelli pipe but there only over in europe,mrp wit stock cylinder i hit 54 mph gps but there really hard too find and since mrp went out of business alot of retailers that carried there stuff is completely sold out

I just did a little fun run to see what it is like with the head work I did. Butt dyno says it helped. I feel like I'm still off on the carb, or my fuel filter is dead. Or maybe even the petcock. I'm going to slap a new, clear filter on and check it when it tries to stall out after a few minutes of wide open, sometimes when letting off to decelerate, but it will catch and chug along with moderate throttle use and allow wide open again. I'm pretty sure it's not soft seizing or it would lick up right, right? Checking the plug isn't proving too useful. A cht gauge would be useful, but the super 9 might get mad. She's running too good right now. Maybe I'll get one of those infrared temperature readers, I can use that on the fly and on both, until I get into a big spending mood again and buy a cht for all my scoots lol. I'm probably just going to shorten one of my boss drives a tiny bit to see about getting into that 6mm I have yet to use on the variator. Then put the clear new fuel filter on, take a ride to the parts store in the morning and get some plugs. I feel that my airbox mods didn't own it up to the point that it went from rich to severely lean, but is like to have better proof. |

Hey, Jwhood, that rs has a bigger chamber than the next r, right? If it's similar to my super 9's pipe then it is. If you ever want to get rid of it let me know |

In all my experience with dealing with tgb scoots,actually thats all ive really dealt with airleaks are a beotch on these scoots especially around the intake i usually put a little permatex sealant to get a good seal cause that area is proned to leaking,i had so much hassle till i started doing that,also what jet you running,m.j that is??

If you ever want to get rid of it let me know Yeah the mrp pipe belly is substantially bigger then the technigas pipe i ran both and definitely like the mrp pipe ill get you a picture up tomorrow on the mrp pipe |

I can assume by the pictures on the site that it does, but I'm not sure how much they vary by Scooter brand. So, you're getting the kit from the Canadians, right? I can't fully justify getting such a good kit if I'm running crap everywhere else. I think I need to look into buying a variator that closes more. I made a mild attempt at filing and grinding the boss drive. That was a fail. It is harder than any bits and files I have. I got no where... |

My bad i meant next r,had the rs2 on my mind for a mina clone 90 build that im gona be starting soon,only bad thing is is that its hard to find a hpc crank for morini that can handle 10000 + rpms,i just got a malossi hpc crank last year but the end where kickstart goes requires a different kickstart unit off a italjet formula 50 with the morini engine,all im waiting on is to get a new stator for the new malossi crank as im converting a tgb to liquid cooled and the tgb stator is bad plus the flywheel didnt fit without being shimmed with a piece of shim stock,i here you on buying kit but i think i found a bgm hpc crank that will work on the morini ill keep you posted

OK,I ran the numbers,dont waste your time with it!No hope as the angles are all wrong,all built to 'look' like an expansion chamber,,I'll call it a "Foo-Foo Pipe"...  |
