Temperature is -10 elevation 500 feet from sea levelHad you make a plug test? Engine healthy pressure test? Even if it's rich where is no way to cut down...

jimmy2450 Posted December 23, 2016 Author Report Share Posted December 23, 2016 Keihin pwk 38 mm no clue about the style of porting that have been done just know by looking that its been done. Needle pretty sure that its the factory one Quote Link to comment Share on other sites More sharing options...

Sandking Posted December 23, 2016 Report Share Posted December 23, 2016 Don't go to 190 until you do a plug chop, I was at over 200 with porting. Quote Link to comment Share on other sites More sharing options...
Sandking Posted December 23, 2016 Report Share Posted December 23, 2016 Depends on porting ^ Quote Link to comment Share on other sites More sharing options...
jimmy2450 Posted December 23, 2016 Author Report Share Posted December 23, 2016 Went to the store end i got 190 and a 200 but didnt have any pilot jet in hand. His it still worth it to try swapping the main by itself or should i wait for some pilot jets Quote Link to comment Share on other sites More sharing options...
jimmy2450 Posted December 23, 2016 Author Report Share Posted December 23, 2016 The pilot jet inside his still the one that comes with the carb its a 58 Quote Link to comment Share on other sites More sharing options...
jimmy2450 Posted December 23, 2016 Author Report Share Posted December 23, 2016 Bought this shee from a kid a month ago he did put a lot of bling bling on it but i dont thing he knew what he was doing! Quote Link to comment Share on other sites More sharing options...
Sandking Posted December 23, 2016 Report Share Posted December 23, 2016 If I purchased a bike used first thing to do is a compression check and lead down test. If your intake manifolds have air leaks your going to be chasing jetting problems with larger jets. 1211, hondabond, or Yama bond on the intake gaskets seals them up nicely. The single carb requires a much smaller pilot and needle taper is critical. Your main will depend on porting. Could be anywhere from 165 to 205 depending on what's done or not done to cylinders. 1 Quote Link to comment Share on other sites More sharing options...

jimmy2450 Posted December 23, 2016 Author Report Share Posted December 23, 2016 Did a full inspection when i bought it compression was and still his around 148 psi im presently building a leak down tester i took the bike all apart got the frame powder coated checked and fix the wiring harness everything his in perfect condition motor runs good exept when you when you hold throttle steady at 50%right jug shuts down Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted December 23, 2016 Report Share Posted December 23, 2016 I've been up around 205 ported on a few. Do the leak down before u continue to ride Quote Link to comment Share on other sites More sharing options...
jimmy2450 Posted December 23, 2016 Author Report Share Posted December 23, 2016 just tried a 200 main jet banshee pulls better still shut down right jug but at slightly higher rpm did a 10 min ride left plug was wet and black right plug was a light brown and wet! so my game plan is im building a leak down tester,i ordered a cool head o ring kit im going to change all the head o ring, and i will buy some yamabond and coat every gasket in the intake and then ill try some more jetting, i really got a feeling that at some rpm range the right cylinder his pumping some air ! but at full throttle they both scream fine Quote Link to comment Share on other sites More sharing options...
