ive got a stock blaster engine with a toomey pipe, 35mm Mikuni carb. Boyesen dual stage reed valves, uni filter on the back of the carb. problem is, while racing last month or so ive noticed that when the engine is cool it runs ine but when it heats up it starts to spit and sputter out of nowhere. it doesnt do this every single time, but about 50%. ive jetted it, adjusted floats and everything else in the carb and it still keeps happening. does anyone else have any other suggestions that it could be? the reeds were just replaced within the last 2 months and the carb is only about 6 months old. i keep it clean and change the plug once a week, gone through my manual and still am not able to solve the problem. does anyone else have a clue? i would really appreciate any input on this before i decide to just trash it!

Thanks

 

Hey i dont know the answer to your question, but could you tell me how fast you blaster goes and what machines you can beat, thanks.

 

top speed so far has been 75 and on the track ive been able to out run everything except banshees and 250r
definately eats 400ex, raptors and all other blasters. or should i say it DID until ive run into this problem! i missed the 2 day race this weekend because of the problem and would like to get back to the track next weekend...i dont want to miss out on any more points!

 

How much did all of your mods cost? and could you give me specifics on exactly what you did to it, thanks alot!

 

75 eh? Little on the fast side?....

 

yeah it is a little fast. didnt think it was that fast until i had it next to my brothers banshee with a trail tech speedometer...top of 6th gear was 74.6 mph...close enough to 75 anyway

 

What size sprockets?

 

75 does sound pretty fast....whats your gearing and tire size?

 

to be honest with you since i started the restoration of this piece with everything ive bought and all the labor time prices at my local shop i wrapped up 7200 hundred so far and now more to get it fixed again.
