no i havent

it looks kike Monterey has a couple of welding shops Grillo and ARC metal fab. San Jose has 18 shops at least three do aluminum welding Fusion welding 408 849 6636, Nams welding 408 287 2114 and Yes Welding. I Think The Welding, Machine Shop would be a good combination. Most any welding shop could ...

Are you going to re-paint the tank? :ugeek: Bictor I believe I might...sooooo many parts that need cleaning attention and paint. Actually have two bikes I'm working on. My time is consumed with running to the sand blaster (Heads and jugs) welded stops on the neck for the Cereini forks today...many ...

where are you located? -------------- Clarence I live in the Monterey area, but San Jose is within 60 mins. I called my buddy in the parts Dept (for years) he turned me on to a gentleman who does boring / honing. Called him today about the Heli Arc request..he's checking into it. Another on the Hod...

Hey folks ~ I'm trying to track down someone who can perform a repair on the left side case where the
threaded stand off was taken out by the chain. Hopefully on the west coast ?

Thanks

Scored some much needed parts for my slow build Rat project.....lots and lots of elbow grease lies ahead

The screw on adaptor is what was used on the original Super Rat pipes and many of the aftermarket expansion chambers. Some of the aftermarket expansion chambers (like Torque Engineering pipes) came with the captured exhaust nut, like what came on the Ace pipes. If your pipe will fit into the screw ...

The amazing part is that it doesn't appear to be thrashed or rusted out. Cool. Probably a motocross build. Yes, I agree...this frame is in much better (relatively rust free) So glad we rescued it so many years ago and had been stored in my garage attic where it was bone dry. I discovered the double...

I used a 94 Wombat rear fender. Cut about 6” off the back, about 1” above the tail light mounts. Drilled new mounting holes. The Wombat mounting holes will end up being the rear number bracket mounts 5B3EFC6B-605A-4EF5-B015-917C541DE456.jpeg NICE looking build you got going on there.....would like ...

the second frame is not a ace 100 frame the ace 100 frame began with frame number A17384, so A10015 would be a ace 90. the ace 90 frame is a good one also. unless I am missing something here? I still cant think, or didn't know anyone ever flat tracked with a leading link r ------------ Clarence Bei...

On the machine with the added steering head -- that was (is) a "period correct" modification to improve the handling of the machine for competition. And it worked! If it were me, I wouldn't try to walk that back, I'd celebrate it. If you use the other frame, you will NOT end up with a ful...

Man I'm lost what direction to take with my build project..... I think the flat track frame...with the double neck welded on is a Super Rat frame. Motor # M7480 Frame # B- 571687 Apr-1971 But what is the other bike I picked up at the museum ? Engine # P10098 Frame# A10015 If my desired direction is ...

If it’s a 100 with a 4 bolt intake, it’s likely a Duper Rat cylinder. Got any pics? :ugeek: Victor I'll get back to you with the photos of the three cylinders I have....(In Palm Springs this week.) Engine # M7480 (93 A Super Rat) has a bigger four bolt pattern on the cylinder than the other intake ...

Hodaka Dave converted my Super Rat from std to reed valve. :ugeek: Victor Thanks for each and everyone who adds knowledge to my present build. I have one cylinder already set up with a reed valve...and two other cylinder candidates. One with a four bolt (to the jug) manifold and one with a two bolt...

Has anyone had porting done ? And does it make a big difference ? And who does good work porting ? (setting aside thirdstones amazing work)... maybe I'm talking mild porting...comparatively ? While I'm learning a lot about these little engines everyday I think I have the makings of a Hot Rod Rat. 24...

Well i have two frame setups to choose from ...might use that flat tracker for motor testing as that is the coil
that ran the motor I'm working on. Here"s the other choice with the Cerani forks.

I have a question about exhaust systems (the rookie here) My flat tracker (in my post) has the threaded screw into head BIG nut with the splines for taping it around. The pipe just slips between the two loose pieces and is essentially held in there by friction between the two AND the exhaust bracket...

Thanks for commenting Victor, Matt, Tether and Throwchain ~ Appreciate your input much. " You are opening the cases anyway so the truth will be revealed in 3-D at that time." (Matt) Yes...I'd like to split both of my M motor cases at the same time. The one with the kick roller retainer dam...

Thank you sir....will look for that.

Can you tell me what part# that is on a 93A SUPER RAT schematic chart ?

New to this engine...haven't split the cases yet and I'd like to learn ahead of time what to plan on replacing .

Thanks so much

I’d say yes use something. I would use Permatex form a gasket aviation sealant https://www.permatex.com/products/gasketing/gasket-sealants/permatex-aviation-form-a-gasket-no-3-sealant-liquid/ But as you see there are many ways to go about it. I used that to mortar Harley cases back in the day, Thin...

My son and I called our 650 "The Couch" compared to our other bikes. LOVED the start up howl !!

Thanks Viclioce & Mr Matt~ I need all the encouragement I can get. (seriously) Today I de-greased the P Motor that came out of the Museum purchase bike. My goal was to determine where the barrel was in size. Took a while but after some coaxing I found an 040 on it.. pretty good news considering ...

Thanks bro....now which bike gets the new engine when I'm done ?....or switch frame setups once in a while?

Back to the original question - will an Ace 100 coil work on a 98 Super Rat? Probably not, as they are two different types of ignition system, as pointed out by gearyoliver. The Ace 100 system is a points system while the 98 Super Rat is a CDI system. You can possibly source another CDI coil that w...
