Yes you will have do drill and re-slot but it will outlast and outpower the stock engine without a doubt, I currently have a 3 and 3.5hp briggs powered minibikes my kids ride and the boy is 17 and 6' 160# now. He asked me to de-tune the thing from a 6.5hp because all his buddies wrecked the overpowered machine. You need advice send me a PM and I'll s4end you pics and advise you on the best way IMO to install the briggs. Here is my 10yo girl's 3hp DB that I can ride.

Here is what a properly re-slotted engine plate looks like:
Ace, what do you do/use to get such nice slots? :shrug: Mine never turn out that nice.

You might as well dismount the tire and clean off the grease. It will spin on the rim with grease. Or should I say, the rim will spin inside the tire.

You need something like window cleaner or watered down dish soap for lube.

Here is a quote directly off the Goodyear Tire website:

"A non-water base commercial bead
lubricant should be used since water in
the tire can cause excessive rim corrosion
problems. However, thin vegetable oil
soap solutions with a water base are
approved. Lubricants which contain a
rust inhibitor can be an advantage. Avoid
the use of excessive lubricant Figure 3.1.
Never use anti-freeze, silicones,
or petroleum based lubricants."

I would take the tire off, clean the tire and rim and do it again.
