Hey guys,
Been a really long day of mounting two engine kits to some very tight low rider frames. Had to do some real work on them and one is still only 80% complete.
After a trial run of the first bike, we broke her in for about a tank. A bit under load and a little with no load.
Scenario:
- 66cc china A80 engine kit, 39T, 20" low rider rims
- Running rich as we are still breaking her in ~20:1
- Gutted exhaust
- Low end increased 2X (Most increadible performance enhancement i've ever experienced with a two stroke)
- Bike sounds deep, but incredibly loud (don't mind, I live out in the bush)
- Top end when riding WOT, splatters. Like it's struggling. It will hit the "in tune" frequency for about a second, then splatter for about 5 secs.
Could this be a lack of back pressure as the exhaust is gutted? (seems unlikely to me tho)
Or is this possibly a tuning issue?
Any help would be greatly appreciated!
Cheers
Chris
Tomorrow, i'll upload videos and pictures for all to see. They are looking and sounding awesome.
