I am mounting an "alternative" engine in a '99 X1 Chassis and need to know if anybody has done done a "solid mount" swingarm??? Either solidifying the stock swingarm (pivots and frame bosses and then cutting all engine mounting brackets off) or using a swingarm from another brand bike and welding on the correct "pull" bracketry as Ill still be using the stock "pull" shock... Any help in this would be greatly appreciated. Thanks in advance

Bartel's H-D had a couple S1's with Blast motors in 'em. Whatever they did sounds similar your engineering problem.

Can you connect the new engine to the swingarm mount?

Then you could use the stock isolators.

Rick, the Bartels Blast uses the stock tuber swingarm and a modified swingarm mount to attach to the rear of the Blast motor, but it uses all 3 rubber iso's like a standard S1.

I imagine that the motor would need to be solid mounted at the front too, if the rear were. Homemade 1125R?

I have seen alum replacements for the rubber isolators---

Really? damn! Who used them and why I wonder? Did they make one for the front mount too?
Bartels used to make Aluminum inserts for the original style isolators to stiffen them up (using them on the Blast also), but I've yet to come across something that replaced the whole thing.

I remember reading about that. It was a racer, he claimed he got slightly better lap times. Slightly.

Hey guys.. sorry for disappearing. I was away for a few days.

The alternative engine being used will be a Kawasaki H2 3 cylinder 2stroke engine. It should be a good "marriage" and think that Erik Buell would approve since he has a backround in vintage 2-stroke racing.. LOL!!

I don't have any photos of the Buell project at this time. Its just a rolling chassis w/no engine.... Here is a link to the bike I had to sell to pursue the Buell project.

Yummy, cant wait to see the finished project.I rode the 750 Kaw. what a pisser that was. Light switch power, scared the hell out of you. ON or OFF. (actually my dads bike) I swiped key here and there as a delinquent. I watched that bike of yours go up and up thinking how much will it go for? WOW 94 and change. Good for you.

The difference is the two-strokes Erik was racing were cutting edge at the time.

"Cutting edge" isn't what I'm after Rick. If I wanted that, Id buy a brand new ZX10 and be done with it. The two-strokes I was referring to that Erik was racing were TZ yamahas, which put out less horsepower than what the old dinosaur Kawasaki H2 engine is capable of. People are still very deeply involved with the kawasaki 3 cylinder engines and plenty of "modern" two-stroke theory has been applied via modern Expansion chambers, reeds, and head/port technology. A few guys I know of have naturally aspirated drag-bikes putting out well over 200 RWHP, and I know of a couple of street-H2's that are in the 160-170 RWHP range. The bike I just sold was "only" in the 90-100 RWHP range, but was still quicker/faster than the X1 with its piped/race computered (otherwise stock) 1200 engine in place. The engine that the Buell chassis will receive will have 110-120 RWHP, and as a bonus will weigh 75 pounds less than an X1, so it should be fun.... Once again, I'm not doing this to be "cutting edge". I like the way the X1 handles/stops and think it will be a fun and unique bike at the end of it all.

I like the idea. Some purists might not. Id rather see you do this than take a tuber and strip it to make a chopper. The chassis would be ideal as its built to take the punishment of a V motor. The inline three would put power down well. (IMO) The weight difference would be a big plus also. Want to see pics when you get started,please?

I was merely making the point that those bikes are vintage now, but weren't at the time he was racing them.

Anything can be made faster with enough $$ thrown at it.



Don't get me wrong, I'm not knockin' your idea. To each their own.

BTW, vintage TZ750's were making close 125HP stock, with factory bikes making much more...supposedly around 140hp. The same modern tuning techniques can be applied to most any two-stroke with similar results.

Very cool kawa I was also watching that on ebay. would really like to hear the transplant turns out. wonder how the weight difference of the engines will affect handling? I have a gt750 was thinking about something similar.

amen to that..


The TZ was definitely the bike to beat back in the day, but mainly due to its better handling and better reliability. The H2r (basically the same engine as a street bike) and KR750 (liquid cooled) actually had more horsepower, but couldn't keep bikes together.. The TZ700 had 90 countershaft and I believe the last year TZ750 ended up with around 120 HP at the countershaft. Guys that race them nowdays are getting 130-140 REAR WHEEL out of them due to modern 2stroke technology.

anyways..enough about old 2 strokes. I was just looking for help in the swingarm department. Looks like nobody has done anything like this in solidifying a swinger/engine?

Ill be sure to post some photos once I get the swinger/engine cradle sorted.

thanks guys.

I have a 1972 H2 with 130 RWHP. Very peaky and a beast to ride on the street. 0-60 in less that 3 seconds 1/4 mile times in 10.6. http://img512.imageshack.us/my.php?image=10020556h c.jpg
