Carbon buildup

Wondering if you folks are overfilling the oil a bit, getting too much splash up top at the valves ?

Just a thought. So little oil in the things it is hard to get it right. I have taken to putting a cup in it, which is what it is supposed to take, although some of that spills out.

If you fill your motor on a slant, or the motor isn't mounted level, you would be suprised how much oil you can overfill it with.

By they way, I have the "Super Titan" that DAX sells, and if it holds up (! we will see) it is a LARGE improvement in torque. I think it makes a good engine, the HS, a great one, again if it holds up. Don't know if there is another dealer you can get these from. To try to ensure a long life I got some Tufoil (engine treatment with teflon particles in it) and am using it in my Super Titan. I swear by the stuff for my cars. We will see.

ya might have a point on oil overfill. bet thats how i blew my oil seal. now to figure this out again

Hey don206, are you still running the stock airbox? I took mine apart last year and noticed that the PCV portion of the airbox had a lot of glue in it. I made a few mods so it had clearer flow. If the PCV system is blocked off, it's easier to blow oil seals. I'm running the SBP 4-stroke air filter now, that unit has a proper connection for PCV.

Are you running the Titan with a fricrtion drive,center mount or other?I am wanting to buy his kit but want to know more about them....

The Grubee gearbox and clutch on the 4 strokes are dung-**** no matter what the venders say.

Don't waste your money.

Check out the comments about the HS 4-stroke and the Q-Matic drive system on this site. The Q-Matic drive is American made and "bullet" proof, some have over 10,000 miles on the EZM kit.

In 3 years we have only replaced a few [less than 6] rope starters, and one carburetor float on the motor under warranty.

Have fun,

OK, Lee. I'll check out your site.
Interested in that Q-matic.

Sorry didn't intend to be an endorsment, just pointing out the HS motor has a great track record. When the motor was first suggested as part of our kit I wanted proof, not rumors, about the quality of the 49 CC 4-stroke. I personally tried to "trash" the first test motor [still running great]and often rode 100 mile trips [round trip] in under 3 hours during initial testing.

The motor will survive "almost" anything, but it doesn't take well to running it at 9,000 to 10,000 RPMs for an extended time period [would any car survive WOT in low gear for an extended time period?]. Sadly some drive systems were made with some wild ratios and allowed the motor to wind up tight, and were quick from a stop, but needed about 9000 RPM to do around 25 MPH.

Have fun,
