Derrickc14 Posted June 5, 2016 Report Share Posted June 5, 2016 Hey guys. I need a opinion on this from serval guys. I was doing some hill climbs this weekend on the coal hills. I hit 2nd to climb in the and once i got to the top and started to cruise to a hill i can go back down safely, the bike would not want to come into band. As if i had too much fuel? and it was struggling to get on the pipe. I had to rev it with the clutch pulled in once or twice then it was ok. Whats your thoughts on this? Its not back firing or popping when this happens. Mods are.. 421 4mill serval +6 timing 24cc domes. 170psi Shearer small bore inframes V4reeds 35pwks 50 pilot 1 turn out 155 mains middle clip 80degrees out 700 to 1000ft elivation C12 straight benol mix 32:1 Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted June 6, 2016 Report Share Posted June 6, 2016 What kind of needles do you have? If you turn airscrew out to 2-1/2 does it hang idle? If not might have to drop pilots. It's also hard to diagnose with out have machine in front of me. Could be a lean bog( hollow sounding. Do you have a pingle? If not maybe fuel system not keeping up Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted June 6, 2016 Author Report Share Posted June 6, 2016 Cel. I had it on the fouth clip down then after i had this issue i dropped to the middle clip to see if it made a difference. No difference besides when cruising mid throttle it didnt sound as throaty so maybe i was a little rich on the needle part. The bog sounds deep. Ill have to try 2.5 turns out this weekend. No time this week. When i was talking to Jeff at fast he thought i would need a 52 or 55 pilot but it fouled a plug on me at 1/4 throttle the time i went riding before this past weekend.

Derrickc14 Posted June 8, 2016 Author Report Share Posted June 8, 2016 I have the dual pingle and f.a.s.t. bowls so its got the fuel Quote Link to comment Share on other sites More sharing options...
special06shee Posted June 8, 2016 Report Share Posted June 8, 2016 Try a 160 main and see if it gets better. I also never had luck with cel needles. Im pretty certain i always ran dek needles. Id also try and back down timing to 4. Motor may not like that much timing? Quote Link to comment Share on other sites More sharing options...
special06shee Posted June 8, 2016 Report Share Posted June 8, 2016 Where are you from? I ride in the coal region quite often, if ya cant figure it out i could help ya out sometime if your close by. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted June 8, 2016 Report Share Posted June 8, 2016 I have 160 52 cel mid clip. I have a 4 mil stock cylinder with cpi. I had 155 50 but went up to be safe. Kind of hard to believe your bike that breathes a lot better has smaller jets. Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted June 8, 2016 Author Report Share Posted June 8, 2016 I plug chopped with a 160 and it was on the rich side. Took a pic and sent them to Jeff at f.a.s.t. and he told me to drop to s 155 and leave it. Its gotton about 20degrees hotter out since then so id be on the rich side in the warmer weather. I might have to drop it more dont you think?ill chop it again to make sure. Up top it pulls really hard. Just this loading up shit when i let of is the issue. Im supprised about the jetting to especially with the shearers. Just imagine your ripping a hill full throttle. You get to the top and you full throttle to 3/4 throttle and it just doesnt really do anything. Struggling to climb rpm. Then i rev once or twice and its back to business. I go to trevorton at the piles alot. Ill pm you my number and just let me know next time you go. Atleast a week advance. Quote Link to comment Share on other sites More sharing options...
special06shee Posted June 8, 2016 Report Share Posted June 8, 2016 Post pics of the plug chop plugs. More so then not, people assume they are rich when in reality bike is lean. If its not spittin and stuttering, then its not a rich condition. If its a deep hollow drowning, its lean. Quote Link to comment Share on other sites More sharing options...
special06shee Posted June 8, 2016 Report Share Posted June 8, 2016 And it very well might not be a jetting issue.. Quote Link to comment Share on other sites More sharing options...
