hard to start

[Yamaha4ever]

i got a 99 banshee fmf fattys with powercore II silencers, bord .65 over ported and polished...boyensen reeds, about 15 hours on fresh top end. weisco pistons... well anyway it takes a while to get my banshee started... i replaced the coil and boots. new plugs... it takes 5 or so minutes to start sometimes less... it will start and die start and die and finally it will roar to life and run great the rest of the day... but if i spray some starting fluid down the carbs it stars right up and runs fine... i dont know my jet sizes i will take the carbs off this weekend and update everyone... any help is greatly appreciated

What's your compression at?

[TwistedSheeRida]

^ what he said. the bike will still run fine if you burnt the rings out a little bit once it is running since they will expand when its hot it will start hard

i will do a compression test this weekend and tell you guys what its at

Hey guys.

 

Mine did the same, I did the post a while back on float bowls being switched around. Just check that they are the right way around, if they arnt, your choke circuit will not work.
