Its a 1988 and has been bored over 1 size, ported jug, compressed head (did not compress it to much because I know I wont be able to get my hands on 110 oct. all the time but am currently running 110 as of now.), bored out carb to a 27mm, Wiesco piston, V Force 4 reeds, FMF Fatty Gold pipe with turbine core II silencer, EBC carbon fiber clutches, K and N air filter with stock CLOSED air box, oil injection still hooked up and running Belray si-7 full syn. injector oil.
Chain is new and is at the stock gearing. The tires for the dirt are ITP Holeshots front and rear. (rears are AT 20x11-10 and front 21x7-10. Thought they would be a little smaller than the stock ones but when I went to pick them up they were a little bigger.) Most of the time I'm on the sand dunes and I have ITP sandstars for the rear 20x11-10.
Right now I wont run it under 50 degrees but hear in Michigan I would say 70-80 degrees is the average temperature in the summer. Elevation is about 850 above sea level and I set the carb settings back to stock beside the main jet, have never changed the pilot jet, the needle is in the middle setting, (I think that's stock?) air screw is 1.5 turns out and my main jet is a 260. (my blaster had a 220 main stock as it was a early blaster.) my plug is a BR8ES.
I have a 10 pack of spark plugs so I can run a plug chop but every time I do it its either burnt or soaking wet! sorry I pitched them in the trash a few weeks ago, ill do it again this weekend and post pics. Ken told me to start out with a 330 main but it was running so bad that I went to a 250 since my dad told me that he doesn't think it would need to jump that much like maybe 2 sizes so then after running it, it seemed to lean but ran a little better. put a 260 in and the plug looks good full out but wet if you let it idle or are in mid range. When you have it full out too it becomes a little boggy after it get the rpms up. (that's with the 260)
I'm totally lost on this jetting process
I'm about ready to hand it over to someone else and have them deal with the jetting because its been a month now and haven't been able to get it right. Need it done by the 2nd of April because I'm heading up to Silver Lake that day and going back up that same Saturday.
Also replaced the pepcock and using fresh fuel without ethanol. (I know 110 goes bad fast but not over night) I have ran 2 tanks through the new motor so it should be broken in by now.
