I’m rebuilding my engine from the ground up. I’ve been searching for a complete gasket set to make it a bit easier. I’ve only found two vendors that have complete sets. Natural and Athena. I’ve found some Cometic gaskets at Schnitz Racing, but these are individual gaskets and a bit pricey too. So I’m not sure if they are worth it. Might be if they seal well and are reusable as claimed.
So any suggestions as to quality of theses kits vs. individual Cometic or OEM gaskets?
FWIW, I am also going to replace all rubber seals in the engine and all wearable components. So far, that really means the cam chain tensioner assembly as I’m not sure what else to consider. I’ve thought about a new cam chain. These are not really expensive from third parties. Although, not sure if the quality compared to OEM. I’ve seen Hot Cams, Moose Racing, and a few unknown - to me - brands.
Well, not to worry on the base or head gasket as that’s included in the EM 719cc BBK. I’m more concerned with the bottom end as I’m going to split the cases.
While it’s open I’m replacing all rubber seals & o-rings and might even go so far as to replace all the bearings and bushings. I haven’t really decided on the bearings & bushings as some have a hefty price tag. If it’s bad it’ll get replaced. But I’m doubtful any are really worn with only 14K on the clock.
I am replacing the tensioner assembly as it’s fairly inexpensive. Even a new OEM cam chain IS under $100. The balancer chain though is over $200. What’s up with that?
FWIW, I’m only thinking of replacing these items as I don’t want to tear into the bottom end again if I can avoid it.

The price difference between a balancer chain and a cam chain? When you actually see the two chains side-by-side, I think the answer will be obvious to you.
Why replace serviceable, operational parts (such as cam chain tensioner, balancer and camshaft chains, and low-mileage functioning bearings)? Your bike, your money, your choice. Just wondering!
By the way, I had a brief chat with EM and he also suggested OEM gaskets. So I’ll be making a list and checking it twice before I order them all.
I’ve seen a reference for Yamabond for the center seam. Anyone know of any other recommended products to seal the center seam?
I know I’ll need to check the oil screen a few times afterwards to clean out any potential parts of the deal that break off. Hopefully I can keep that to a minimum with careful application of the product.
I believe that KawasakiBond & YamaBond centercase sealants are both manufactured by ThreeBond. Should be available thru any TuckerRocky / WesternPowerSports, etc aftermarket supplier. Current # is TB1184.
The secret to successful use of case sealant is a very thin coat on both halves of the case. Not an 1/8th inch bead on the RH side, that is what makes 'gummy worms'.
The only part I do plan to get treated is the transmission with the micropolishing. Not sure who’s going to do it, but for $120 I’m willing to try it and see if it does provide a smoother shifting transmission.
Whoever quoted that price ($ 120) apparently is NOT the firm whose website appears from the link (https://www.cryoheat.com/motorcycle-atv/4-stroke-2/) you posted, ILove2. Rather, $ 399.98 is shown as the price for transmission micropolishing services from that vendor.
You're in southern California, where dynamometers exist in considerable number. Dyno your bike, essentially stock, as it is now, and save the charts. After you've hopped-up the machine, dyno it again, noting the performance increase; please share the data with the website.

I’m trying. So far nothing in the local area. I’ll probably have to push it out to something within a 75-100 miles. I’ve been looking. I’m in the Coachella Valley - Palm Springs - area.
I think there might be something in the RedLands area as they have a speedway out that direction.
Ah-Ha! Found one in Palm Springs. Maybe. Need to call, but their website actually has it listed and only costs $100 for a baseline test - two pulls.
So, quick question, tire matter? I have street tires I can mount or use my current tires. Kenda K60 rear and Michelin K65 - I think, it’s no longer made - front.
