Dell' Orto SHA 14/14 Problems.. Running too lean with new Jets

Hey there isnt a needle in the 14/14 Del. Have you check to be sure there isnt a air leak around the carb area? I still thing you need a bigger main for that aircooled motor. All that oil coming out of your exhaust is from being to rich with your oil in your mix that it cant burn so it leaks out of the exhaust. Your over run may be what is called a lean over run.

I know at times when I check the compression I would get low readings and found it to be leaking from the fitting on the gauge. So I since started using some sparkplug thread sealer on the fitting and on the sparkplug. Your pulling the start until you cant pull no more when testing right plus let it set for say 10 minutes to see if it holds the pressure to. Have you checked the your reeds are sealing good to by holding it up to a light while looking at the motor side. Some times you can over tighten the screws and make the reeds warp so they done seal good.

Plus I think you need to make sure your clutch is set close to 8500 rpm's to or it can seem like a carb problem and that maybe why you feel that power lose in your bottom end. If its not set close it can make you chase your tail tuning the carb.. Heres how I go about setting up the bike. First we need a idle than I check for a airleak than set the clutch than tune the carb.

Tell me what the springs are set at and measure your clutch and tell me what it is and your clutch bell to. Your clutch should be 2mm smaller than your bell. If its way off that can cause your lose in power in your low end to.

Those 14/14 carbs are pesky..I had one on my $30.00 half fairing cag..Those plastic flatslides errode fast causing airleaks and the float setting is crucial aswell as carb angle..The rubber shields at the cables are crucial aswell as the small gasket sealing the carb top.........I also had to modify the fuel banjo and drill the carb body to aid more fuel delivered to the carb faster aswell......

What I like to do is set the float rich so it overflows then set the float just short of overflowing and I do it with a spare gastank on a bench with a 14x14 shallow pan under the carb to save time..After setting the carb perfectly I install it onto the bike to check the tune...

Seeings you just re-used the cylinder and didnt hone it Id say youre not gonna get nearly the performance as you should.....

So I put the 82 Jet in to see if I get an oily plug. The plug is black this time... So looks like your right again Stray. I think it did have the air leak so it was running lean with the higher jets. Now that the possible air leak has been fixed it seems to be getting oil again. So looks like I need in between a 76 – 82 It maybe held onto the RPMs a little still with the 82 but it did it more before with the 80 and the air leak that could be fixed. or not? lol I don’t think it’s getting the compression I want but I’m not going to buy another ring and Piston. Going to wait till I can upgrade to the L/C 50..

I never found a SHA 14.14 specific manual but here is the parts breakdown if any one needs it. The Manual I found is just a general one and the forums won’t let me upload a PDF.

N!pples

Another update: With the 82 it was running like crap so back down to the 76.. Higher than the lean 74 and sounds good and strong. Let’s hope it mixes some oil.. Seems to be dark after my few warm up runs..

The looser the clutch spring nuts the sooner it engages and assuming the further the reach... Think I got it..

Cheers!
