I haven't ridden it since I got it working but I got the seat and everything back on and it's ready. We just need more snow as we lost some this past weekend. Pickup line in fuel tank was fine but my question is this. The fuel filter sits vertical in the tank and it has the white tube around it keep...

Update! Well I think I am onto something here. I grounded the engine to the chassis, turned out the air screw on the carb one more full turn so its 2 1/4. I was running it at 1 1/4 last year so that's where I left it. Added another gallon of fuel and gapped my plugs to .031. It started up on the thi...

I do have a different used exhaust pipe I can throw on there in testing or I'll try it without. I'm gonna ground the engine first before I try it. The sled sat in my garage attached to my house all summer long covered up. I highly doubt a critter got up in there and built a nest of some sorts but wh...

#13 on the diagram is the plug. I have it in the center hole of the 3 surrounding the main.

TORS has been bi-passed since I've gotten the sled.

Hi Chuck!

The carb I have is a mikuni butterfly. Here is a diagram of it.

Tonight I cleaned the primary clutch, I did find one roller that was loose but since I don't have the part to replace it with currently I just put everything back together. I can now almost rule out the primary. Secondary opens fine and closes by itself. Could use a cleaning yet. Never got around to...

Now this is a Mikuni on my XLV Bob. For the longest time I thought it was a Keihin but its a Mikuni.

I hear the Keihin would be a better swap. I don't know Chuck but maybe he will see this and chime in. Thanks for the referral.

More imortantly thank you for the much needed assistance!

Thanks for all your help here and on the other site Bob!

Yeah I'll give the pilot screw a try and also in regards to the secondary. The spring seems fine, I can open and it closes

Where can I get carb parts like a seat assembly with needle and pilot screw if I need???

Also what about my air screw being a potential problem. I am currently at 1 3/4 turns out. I notice the tip of the needle is ever so slightly bent. Do I not have the screw out far enough, is this maybe why I am getting a bog and not very good acceleration?

Thanks for the help vmax540! I never got to the clutch tonight but here is what I did. I re-adjusted the plunger so there is just a little play, no change. I put a clamp on the pulse line going into the pump and also one on the line going to the fuel pump to ensure no air leak. I bought a new pulse ...

Could that happen just sitting a summer in my garage? I know nothing about clutches. Please advise what I would look for
Even better if there is a video I could watch.

Thanks for the reply!

Please help me. I was referred here from Sacha Hindle SRV540 proboards. I have an '85 Yamaha XLV and I am stumped beyond belief. History: Newly rebuilt engine a couple seasons ago New Boyesen reeds at same time Newly rebuilt fuel pump (as of yesterday) New fuel filter in tank New plugs, tried multip...
