Royal Rods

Has anyone here had any experience with these conrods?

I've heard good reports from Maico and KTM owners/builders.
At the moment they do not produce a conrod for any Husky other than WR360 Huskagiva, 610, 630 and 97 on 125's.
Is there enough demand for these if they were to make a rod to suit 250/400/430/500 engines?

Dave Pratt has a nice rod kit for the Swedish bike. 125 and all others (not sure on 500) tritrophy on e bay. great product

I tried communicating with them and had no responce. let me know what you hear.

Please note , would want a bit higher grade of steel if I remember what their standard was. Have to go back and check

here is a link to the question I asked on 2 stroke

That's interesting Gary, I've seen to a couple of builders posts, Toby Opferman is a well known Maico dude who says they are good quality and a couple of KTM guys who recommend them as well, maybe they have improved over the years?
Tony.

He has none listed at the moment, I will message him to ask if he has any.

Really its just a geek thing ! That metal type can work. Always looking at the utimate possible part or parts

What issue did you have with Hot Rods? I was impressed with their product after getting a 79 YZ250 con rod for a 250WR project I have going. It was more to save a good conrod to create a second 430 engine as I was going to build a 430CR. Since I can not find a 1982 CR frame, I am going to build a 1983 250CR and do some experimenting with porting and expansion chamber

I can't find a listing for 400/430 rods on their site, do you know if they make them jimspac?

Try him yet?

They do not make them. I was looking at rods they make that have the correct center to center dimension, the small and big end bearing journal sizes. I was going to check into having Hot Rods make rods to the specs that we need from the existing forgings that they would just machine to specs.

I stopped after Gary wanted a bigger order but I believe he would have had to pay for the developement of the forging process. That is why I looked for the forging numbers that the 135mm con rod and the 500 could be made from forgings that were already developed. I was trying to avoid the deal breaker by doing the research myself.

No, I haven't Steve, but looking at their site, they don't list a 161990201 conrod, would the 161982501 (79-86) rod work?

Never had to deal with replacing a rod, no idea.

240, 250, 400 and 430 share a rod, it seems odd that the part number changed, the 85 400 rod vs the 87 400 rod being a different number seems very odd
never really paid attention to that, now to wonder why, where is George when we need him

These Rod Kits are NEW Manufacture, not NOS.
They feature beautiful Rod Design, Heat Treating, Ti Caged Bearing and 25.03mm Properly Heat Treated Pins.
We have been having these kits and 125 Husky Rod kits manufactured for some time with Great Results.

Just received an email (not an eBay message) from Dave, I'll be ordering one of his rods I think, thanks Joe.

I did read somewhere that the 87 and 88 rods were a little lighter in an attempt to reduce vibration.
Tony.

The 87-88 rods on cranks I have or have had are shaped more like an I beam than a popsickle stick. There are the little recesses at the wrist pin similar to the ones at the big end on the picture in post #17 above. I guess for better oiling. Never had one out of a crank so can not weigh but weight difference being lighter never came to mind looking at the differences.
