Jared23x Posted January 15, 2020 Report Posted January 15, 2020 Here is my problem I am having trouble with low end power. It bogs as soon as you take off. It is impossible to wheelie even with pulling as hard as you can, but if it just sits there and idles it is fine. When you rev it, it feels smooth and comes right back down perfectly. It is only when you crack the throttle. The mid range and top end is fine it runs good. Once I noticed this I did so much LITERALLY 200 hours of trial and error. Nothing worked so I rebuilt the entire motor. Hot Rods crank, new pistons, everything, I mean everything. 800 dollars later I fired up the new engine and it did the same thing. Bogs off idle. I feel like it would have to be carburation at this point. But I have tried all jets and needle positions and nothing works. My new motor has 150 psi in both cylinders and no leaks (with tester). Carbs are spotless I'm running 30 pilots and 340 mains on the third clip. 30 might sound big but thats what the bike likes at idle. Please comment with any suggestions. Thank you. Quote

Deets Posted January 15, 2020 Report Posted January 15, 2020 Where are your air/fuel screws set? Quote
the boris Posted January 15, 2020 Report Posted January 15, 2020 What about air leaks, did you check that? Sent from my VOG-L29 using Tapatalk Quote
Jared23x Posted January 15, 2020 Author Report Posted January 15, 2020 My screws are 1/2 turn out. Which is to far but i dont know if that would create a big bog. I ordered 32.5s and they should be here tomorrow. And i had no leaks when i did the leak down. Quote
christoph.tamz Posted January 15, 2020 Report Posted January 15, 2020 Your lean. That’s why your blowing pistons. Try 1.5 out. Did you plug chop? Are you sure your carbs are clean?Sent from my iPhone using Tapatalk 1 Quote
the boris Posted January 15, 2020 Report Posted January 15, 2020 Maybe you do have to much fuel, flooding the cylinders. Did you rebuild the carburettors too? Sent from my VOG-L29 using Tapatalk Quote
the boris Posted January 15, 2020 Report Posted January 15, 2020 Did you pull all the jets out, even air jet too, and clean all the veins. Sent from my VOG-L29 using Tapatalk Quote
Jared23x Posted January 15, 2020 Author Report Posted January 15, 2020 Ya carbs are completely clean ive literally cleaned them probobly 10 times. I took out the main jet tube, pilots, air jet, neddle and seat, everything. And turning my air screws out makes me more lean and my idle revs out to limiter. Or it will hang really bad. I feel like me going to 32.5 on a mostly stock motor is way to much but thats what it wants idk. Quote
christoph.tamz Posted January 15, 2020 Report Posted January 15, 2020 What’s your elevation and tempsSent from my iPhone using Tapatalk Quote
Jared23x Posted January 15, 2020 Author Report Posted January 15, 2020 2000 ft and its 20 right now but summers are 80. And just to explain again the mid range and top end hits power band and runs as should its only right off idle when you give it throttle when it bogs. It makes it impossible to ride hills because at that low rpm there is 0 horsepower. Quote
Jared23x Posted January 15, 2020 Author Report Posted January 15, 2020 So unless you hit a hill going 20 mph at least your not going to make it up. If tou start slow at a hill it will bog out and die no matter what throttle you give. Quote
