Looking for first time Pregen maintenance tips

[lolibater]

Hi everyone. I'm about to do my first maintenance on my Pregen this Saturday. I will be doing the following tasks:

- Oil change
- Clean oil screen
- Coolant flush
- Brake fluid flush
- SS brake line install
- Replacing shift shaft oil seal
- Change spark plugs
- Adjust valves

Does anyone have any tips, either model specific or general, that will make this easier for me? Anything to clean and/or check while I'm in any of those places? Thanks.

clean and lube your chain, also since you will have the bike apart already scub anything you cant normally get to when you wash it.

[lolibater]

I surely will be scrubbing and washing anything I can. I hear lots of nasty **** piles up under that front sprocket cover. That should be interesting lol.

valve job.

Be sure to change the oil filter

[lolibater]

Yep, i got the filter and all gaskets and washers here already.

I was more looking for specifics as to how any of the tasks I listed might be accomplished easier or faster? Any typical issues I might run into that as a first time worker, might not know about?

Take the fairings and tank off the night before so you wont have to deal with it the next day.

Valve job: to make it easier if you if you can get the right side coil bracket off. You wont have to take off the radiator or even move it to get the valve cover out. If u can remove that bracket (its two bolts and a spot weld the size of a bb). Make my valve job alot faster.

Spark plugs: Use anti sieze and make sure to install them correctly, meaning dont over tighten them but get them to sit in right.

Everything else is straight forward on doing the coolant flush and break fluid. Would be easier if you had everything on the center stand for sure.

For coolant flush, don't forget the drain that's right under the head on the front of the engine.

idk if you've done a coolant change before, but it's not bad. It helps to have a second person there so you can watch the radiator bubble while the bike runs. It only takes a minute to get the bubbles out.

For the SS brake lines, use a lot of force when compressing the brake lever. It will force the air bubbles out of the lines better. The whole process of bleeding air out of the lines takes about a minute once you figure out what the heck you're doing.

Your gonna have a fun weekend! I enjoy working on my bike. Ummm don't drop your feeler gauge. Haha. My first valve adjustment went well until I dropped a feeler gauge and it feel down the opening by the cam chain. Luckily I was able to get it out after removing the clutch cover. But it sucked.

Also, how important are the following:

- Replacing fork oil
- Getting suspension "adjusted" for my weight?
- Lubricating swingarm pivot

[choneofakind]

Swingarm maintenance, do it!! Makes the back end smoother. Worth the time.

I swapped to a little thicker oil when I had my fork seals replaced. Seems a little better.

There's really no tuning for your weight on the pregen shock

If you're gonna do that, buy some correct-sized springs from Racetech and cut some new spacers. It will make a world of difference.
