Excellent instructions, jetting spot on - took away all the guessing. Completely transformed the bike through the rev range.

My 2008 T100 was running pretty rough after I'd fitted a TEC 2:1 pipe, K&N filter and removed the airbox baffle. Primary jetting was not great.

Anyway I fitted the larger jets and a shim for each needle, adjusted primary jetting in line with TTP's excellent instructions (see link below) and its mint. Totally transformed the bike, and has really released the power!

I also fitted TTP coil and HT leads as the old ones were rubbish and it kept cutting out int he rain, not anymore though.

Great products and great service, highly recommend this kit.
