What is doing or not doing? What was the last repair or maintenance done to the bike?

We need lots more info Yr motor size, does it idle, have you serviced it since 1990 etc.

Welcome to the board!!
IMHO the best one around !!!

Check the fuel system,run check on fuel pump if so equipped,if its been sitting a real long time make sure nothing aint up in the air intakes,and you have replaced all fluids,also checked n tightened all bolts nuts & look over wiring and plugs and replaced any frayed or broken parts.Also make sure all vacuum hoses are tight and placed prperly and any seals at manifold are inspected.

stay safe & enjoy the ride!!!

Probably could use a bit more info...

When you say won't accelerate do you mean it just dies, is sluggish or what. In neutral will they engine rev up or does it pop and spit.

Also a little more about the bike... year, engine size, mods (if any), recent work done...

Anything been replaced lately... spark plugs, air filter, etc

Help us help you!

ty all 4 responce...blasted thing run great in neutral but put it in 1rst it bogs down and shuts off.fluids new and carb is great.

1rst let me say i`m sorry for being slow on replying....i have a hugger spotster 883 with less than 1000 miles on it. just did all fluids and fuel system including cleaning and putting in a fuel pump and plugs too.it sat for 2 year prior to doing this work...thanks for all the replies and again i`m sorry for being slack on responding back

Check the tension on your drive belts/chain. It will bog down if their over tightened. Did you check the petcock filter in the tank. I always use Sea Foam in my bikes to help them run clean. Try it, it could fix your problem and it is only 8 dollars.

ty wil check bbsooner

WELL? Is it running now? What was the problem... or problems?
Update us, please!
