PK Info Required - Technical

[jambo]

I am needing some advice into which type of oil I should use when giving my recently purchased 1992 PK 100XL an oil change? Also how many miles (or months if not used a lot) do you recommend for an oil change?

Also my exhaust for the above Scooter req’s replacing and I have a couple of questions which I hope someone can help me with

1. Would going for a performance style exhaust give me much performance or acceleration improvement on my bog standard Scooter rather than a standard exhaust replacement?

2. If I opt for the performance exhaust do I need to rejet my carb which I have read about somewhere?

3. Can you recommend an exhaust and supplier including part number for recommended exhaust? Hopefully someone has already done this and can recommend an actual make and model including all the info related to any extra work required to engine.

Finally

4. Is it relatively straight forward to fit the replacement exhaust?

Thanks for your patience with the above, totally new to Scooters after having a serious soft spot for then for years. Hopefully one day I will be able to give the advice rather than ask all the questions!

Thanks again,

Jambo.

Ok here goes (until someone disagrees!)

1 - Go to a proper scooter shop and ask for Vespa Gear Box oil (SAE 30) I reccommend plutoline. Or buy some mail order from beedspeed etc

2 - i change my oil once a year, at the start (or end) of the Rally season. Top it up every now and then.

3 - Sports exhaust would improve performance depending opn which one you choose. Everyone has a different favourite. As for PK100XL I couldn't reccommend one, someone else on here may be able to

4 - Will more than likely need to re-jet, again, I can't advise, good shop or someone with experience on here may be able to. Engines are all different though so you may need to do a little trial & error.

5 - Polini I think would probably be a good place to start. Leo Vince Secsys maybe?

6 - Should be easy to fit. 2 skinned knuckles 1 blackened thumbnail tops!

Cheers Breezer

Thats some good info to get me started, thanks a lot. Like the 2 skinned knuckles 1 blackened thumbnail tops!

Jim's right but I buy cheap SAE30 from the local car shop,I agree once a year is plenty to change,just keep an eye on the level.

Exhaust wise I'd use the LeoVince Secsys,I think Hank got his from Turners of Merseyside for a reasonable sum.If you buy from them then get a few extra jets sent too,check the size of yours first as I don't know which size the 100 runs.

The spanner work is pretty straight forward but I'll raise Jim a grazed wrist and a bunch of expletives. ;D

[breezer]

I'll see your spanner and raise you an electric drill, rasp and file...

Turners - fantastic! If your gonna order owt from them get the oil n lot in one go save on the postage!

For the price get a couple of new oil bolts and fibre washers as well. Also:

DONT overtighten the oil nuts, cases are ally and will easily strip threads. Finger tight and a 1/4 turn with a spanner!!!!!

[jambo]

Loven all this info guys! Will certainly have a search for Turners now and look forward to replacing the exhaust some time soon so I can let you know the damage that I inflick on myself whilst changing it!

[jambo]

Sorry to trouble you again but does anyone have a web address or contact number for Tuners of Merseyside, have tried to google them but no joy.

Thanks again

I got a leo vince a month ago - the one that fits PK80/100/125's,
think it was about £55 + postage

ring them, they are quite helpful

[breezer]

Yeah, VERY helpful

Even at 10 past 5!

[jambo]

Thanks Hank & Brezzer for the contact info for Turners

Hello Hank

The leo vince that you bought and recommend will it be a straight forward removal of the original exhaust and fitting the leo vince exhaust? Have read comments about fitting elbows etc with some replacement exhausts?

Thanks Jambo

[Juan]

I can't remember if the Leo uses an elbow but if so then get a Polini item as the standards are very restrictive.Hank'll be able to tell you.

[hank]

sorry, didnt notice this question before today. no, it doesnt need the elbow. i had to drill the holes out a bit to fit onto the cylinder, which is a DR135 ( ) but otherwise, good fit.

[me]

for info the PK100 uses a 19mm delly with a 76 main i'd go up to 80-82 on the main when running a perfomance pipe (if you call the Leo performance), if you have the plastic air filter i'd drill a few 10mm holes in the section before the round metal filter, you'll see what i mean when you take the air filter off. About 6 holes will do.

[jambo]

Thanks for the info Hank & Me

Just collecting all this info for here there and every where which is fantastic and feel like I am getting some place now. First Scooter and it's a lot to take in. Seems to run fine and is totally standard but looking just to add a performance exhaust as the one fitted needs replacing anyway.

Plan to take engine out over the winter, clean up patches of rust, hammerite the lower surface and inner shell and get the outer sprayed. Not sure which colour to go for though?

Thanks again lads, much appreciated

Jambo.
