Bad gas story

[Mat]

Did you turn the eng' over a few revolutions then put the cams back in the correct positions and recheck?... Just to be sure.

Yes I did at least 3 revolutions before checking back the gap.
I did check twice but towards the end I was excited and tired at the same time so I decided to call it a day for now:hypnotysed:.


Also I had got my hands on the proper torque pattern (inside to outside) but forgot where I've seen this


The gasket I had ordered off ebay wasn't the correct one so I crafted a new one with some Felpro I had. Did I read somewhere some ppl spray it with WD40 to be able to reuse it next time they do valves? I'd be happy not to do paper construction too often, wish there were some real gaskets (silicone) available for my model.

Yes, I would double/triple check your measurements before you close it up. Make sure the cam shaft end notches are in position A to measure L intake as I noted above.

I wasn't doing it right, my brain was half-working yesterday night and I was doing the left intake valves at the wrong cam position. The bike idle well so I'm going for a test ride and see how it goes.

You wouldn’t want to use a “Real Gasket”. They’ve been known to cause problems in this type of engine with the tach drive in the valve cover. The gasket squishes too much and causes problems where the tach drive meshes with the worm gear on the exhaust cam shaft. OEM is best. So I’ve read.

Good to know about Real Gasket.
When people say OEM, does it mean they can order from Suzuki direct or it's old stock on ebay only? I guess old stock only?

I'm a little better at doing my own gasket, still spent a couple hours on it but no leak at least.

BTW I'm happy to report I just did a good ride without any problem Could never gone trough it without your help all
My dad (PO) was quite impressed to see all that help I got

Congrats Mat, learning curve, now that you've done it, pretty simple from now on.

OEM= Original Equipment Manufacturer. In this case, yes, made by Suzuki. It’s nearly impossible to know when you order online from one of many sellers of OEM stuff whether the item has been manufactured recently or if it’s NOS= New/Old Stock. My guess, because these are 40+ year old bikes, Is that most OEM items you find, whether from a dealer or eBay/other is NOS. But I’ve bought OEM gaskets from places like Partshark.com, babittsonline.com, the now defunct bikebandit, and ebay, and I have never gotten one that wasn’t in perfect condition. Doesn’t mean it can’t happen. I’m not sure what reputable websites ship to Quebec. Maybe another Canadien will chime in.

Just wanted to let everybody know that since I adjusted the valves and made a solid connection on the ignition coils my bike ran fine 99% of the time, hot or cold.

Went on a 500 miles trip with heavy hills and only had a couple issues.

First issue I was towards the end of a long ascent and the clutch started to slip for a moment. Motor did rev up from 5000 to 7500 rpm in a moment and I felt the lack of propulsion. Problem did clear by itself after I downshifted. I guess I should check for clutch adjustment only and not plates or springs yet?

Second issue, still in a big ascent at high rpm, the bike rpm suddenly slowed / bogged and that felt as if it was gas starved... I'm not sure I should check for what in what order? carb / vacuum or petcock?

I'm interested in sourcing ethanol resistant orings for the carb and petcock, where to get that in 2023?

I'd check the clutch cable for proper adjustment first since that's easy. Are you using the correct oil? The wrong oil will cause the clutch to slip.

As for the bogging issue, you said it happend while climbing a hill at high rpm. Between the steep incline cause fuel sit at a different angle in the bowl in relation to the jets and high rpm high load for an extended period of time, maybe you drained the bowls faster than the gravity feed could replenish the fuel.
