TBR7 with PWK carb needing help

twinmonkeys · 07-26-2020, 09:47 PM

Hello all I am in Northeast North Carolina and new to the site. I have been lurking and learning for a couple of years . I purchased a TBR7 in April and done after market exhaust, and pod filter with a PWK 30mm carb and oil cooler.

The bike has 700 miles on it and was OK since changing the carb. Problem I am having is dialing it in. I have had OK luck with 130 main, 35 pilot and needle on 1 up from middle. It will pull hard to 6000 and then starts pissing and popping. I have gone up with main jets down with main jets same with the needle and pilot doing 1 adjustment at a time and seeing how it works out.

If I go higher then the above setting the bike misses farts, fouls plugs and can't be ridden. With the setting I have a plug that is white and no coffee or coco color to it. I am worried about it being to lean.

It is also a little hard to figure out since in the morning it can be 70 out and by the time to head home it maybe 95 with 90 percent humidity.

Thanks in advance for any and all help.
