Hi Guys, please help

[red-eye-righley]

I have now found 2x H series bikes for what I believe is reasonable locally, I have also found what appears to be a E series engine. Lets just say that the engine will need some SERIOUS work (full rebuild) and is missing a CDI. Granted I would probably rebuild the H series motor at some stage anyways.

Now firstly, IF it is worth just getting the engine, is it even adviseable. From Dfeckel's build it seems better to rather go with the H series engines if I want to avoid denting the pipe, but I see in this build that a E series was used:

Also, how do engine numbers work for the E vs H series bikes, any way of telling what series it is from the engine number?

And lastly, can one swap cranks from E to H or vice versa? I might have found a seized H series, maybe I can use the two motors to build one.

Cheers guys, any help will be greatly appreciated before I pull the trigger on the first part of the build.

In terms of parts interchangability between the E and H motors, I would get onto Bikebandit or some other parts seller that has the parts schematics. You can compare the part numbers to find out what's interchangable.

Getting the H series PC pipe to fit the E was a pain when I thought I could make it fit without cutting, but not too bad once I finally bit the bullet and started cutting. The key is to either have good welding skills or know someone with the skills. I was lucky to find someone good close to my home.

Step 1. CUt off stinger at the point it meets the end of the expansion chamber

Step 2. Dent expansion chamber to clear KIPS

Step 3. Cut off lower pipe mount bracket

STep 4. Tweak upper pipe mount bracket

STep 5. Make brackets to attach pipe mounts to frame

STep 6. Take rolling frame with motor in place to welder and have him put everything together. It worked well for me.

That said, an H series motor will make pipe fitment MUCH easier.

I agree with dfeckel because the H motor will save you a lot of headache and we all know that we do not want too many dents in those pipes! Good luck with the project.

Thanks guys,

I reckon its time to look for the newer KDX, definitely the way to go for me! I know a guy with an E-series and he says he's got spares issues nowadays - I dont want to finish a bike and then find out I can't find stuff for it, plus I like the fact that the H will fit with a little less persuasion.

Cheers
