REALLY hard to start?!

Peugeot 103, SHA 15/15, simonini performance exhaust, stock engine...

Just put on a performance exhaust, the bike runs pretty good but it's WAY harder to start. I have to pedal and pedal and pedal, fuck with the decompressor and after a few crazy backfires it will start up... then I have to rev the fuck out of it and jump on while it's revving. After i ride it 20 yards or so everything is cool.

I tried fucking with the timing a bit.... retarded it, advanced it. doesnt' really make a difference. What's the deal????

Re: REALLY hard to start?!

loose belt or lean jetting, or both.

Re: REALLY hard to start?!

what's the point & plug gap set at?

REALLY hard to start?!

#CrazyWayne™ rocks. #CrazyWayne /

Condenser weak old points ?

Did the flywheel cam lob wear down points arm closing points gap?

CK flywheel timing & stater ?

Did you clean gas tank/fitings ?

Did you in stall new gas hose/filter ?

Did you clean and re gap/points ?

Whats your timing set at ??

Did you Try a new spark plug ?

Your spark plug is Brand ?? NO#????

Spark plug gap is?

tighten your head.

and belt

Re: REALLY hard to start?!

All I did was put on a performance exhaust. Before that, it started on one kick.

I'm running an NGK b6hs, new condenser, new coil, etc.

I didn't gap it to any specs, just made it smaller until I could get it to start.

TUNE IT to specs .

Don't guess and Pray it will start .

Condenser weak old points ?

O and don't wast or time.

Good luck.

Re: REALLY hard to start?!

Sounds like the belt as far as starting up goes..

Does it idle alright?

Re: REALLY hard to start?!

Once it gets warmed up it idle's fine. But you have to ride it down the street for a sec before it'll idle.

Re: REALLY hard to start?!

update on this... I'm still having problems...

someone else recommended the following

Condenser weak old points ? ---- no, new condenser, points look great

Did the flywheel cam lob wear down points arm closing points gap? --- don't know what this means, but there's no grounding out going on inside magneto, points appear to spark okay

CK flywheel timing & stater ? set to stock

Did you clean gas tank/fitings ? filter is cleeeean

Did you in stall new gas hose/filter ? yes, yes

Did you clean and re gap/points ? only 1,000 miles on the bike, points look great

Whats your timing set at ?? stock

Did you Try a new spark plug ? yes

Your spark plug is Brand ?? NO#???? NGK B7HS, also tried B6

Spark plug gap is? just a little smaller than parallel b/w arm and electrode. Any smaller looks like it would practically be touching

air leaks? nope, checked out, and 120psi

like I said, started up great before I put a new exhaust on.

Re: REALLY hard to start?!

do u have a choke? if no use your hand should start right up if u do it right

Re: REALLY hard to start?!

I have both a choke and decomp, you have to do it _just_ right, and pedal the hell out of it. After that it won't idle unless it's given a good warm up.

Re: REALLY hard to start?!

got a proper spark plug gapping tool.... smallest is .02 inches, so I gapped it tight, maybe a tiny bit smaller. Starts easier but still requires warm-up or else it dies at idle. any ideas?

Re: REALLY hard to start?!

Put in a new plug. An old or dud plug will make the bike hard to start and make it backfire. The only reason a bike would backfire when first started is a weak spark not igniting fuel. Make the plug gap larger. Parallel is pretty close to being correct and should work fine.

Re: REALLY hard to start?!

Naaah, fraid' not my friend.

New plug, stock gap = same/worse. The gap on a peugeot... according to other folks here is between .016-.022", much smaller than parallel. When the gap is parallel, it's harder to start.

Re: REALLY hard to start?!

Wierd. I've never seen that happen with a properly gapped new plug. If it backfires, it has to be electrical...

I'd try running some fine grit sandpaper (220 works) through the points, spray them with carb cleaner, then run a piece of paper between then until it comes out clean. Sometimes a tiny amount of oil can get on points, and although they look clean, the plug doesn't fire every time. Once the bike runs a little, the points are opening and closing so fast the oil can't ooze back.

Other than that, check the wiring over to see if anything is burnt/worn/internally broken

Re: REALLY hard to start?!

thanks, I'll give that a try today.
