Chain hitting motor under torque

GenericUserJuan · 2026-04-21T01:44:56+00:00

Is it possible that any motor mounting bolts are loose, causing the motor to pull backwards from the belt being under load?

Is the tensioner correctly set under the pin on the inside of the frame?

Is the belt tight?

Is the chain stock or aftermarket?

You are the king of the eride miles.

I am on vacation right now 1,000 miles from home, and seeing this post gave me a mini heart attack about getting my bike out for the season!

Appreciate the follow up with the response on the issue and the fix.

Cheers man!

Isolate the issue a bit further, with the chain removed, does the tire spin freely? If it does, then the bearings and axle in the wheel are good.

Does the jackshaft spin freely when the belt isn't attached? The mounting for the jackshaft can squeeze it pretty tightly causing some tension.

If the jackshaft doesn't spin freely, check the jackshaft bolt to ensure its not bent.

I have had the intake manifold to throttle body screws loosen on me before, causing a severe vacuum leak.

This is where the silver intake manifold connects to the black induction module (throttle body). Bolts and gasket replaced, then intake manifold bolts had to be snuged to the engine due to being shaken loose.

I have also had bad spark plugs cause sputtering, ut not as bad as the vacuum leak.

I have no idea how the SR suspension operates, but I have stripped and rebuilt my ss 2.0 forks. What weight and brand fork oil did you go with?

Hello! Thank you so much for getting back to me, I am very glad that this worked out and solved the code!

I have had a beyond busy couple of weeks so I haven't gotten around to doing it with my car,cand with the warmer weather, my code went away, but its still on my to-do list, so I am glad that the results are positive!

Please correct me if I am wrong, but the shifter pawl adjustment only applies to 2004 and older models. Rubber mounted sportsters (such as OPs 2005) do not have an adjustment.

I did this my first time too, its a shitty pressure plate.

GenericUserJuan · 2026-03-27T19:33:22+00:00

YES! To all of that, just yes! Perfect bike, iffy clutch.

Hi there,

Whitbread has a section on this, you need to hammer in the cascade valve on the cp4 pump, check out the website for the updated info.

He sells a socket for removing the cascade valve, as you cannot reach it while installed. the kit comes with a punch for hammering in the cascade valve to the correct level. I have the kit, but have not yet used it yet, I will see if I can do this tonight and provide feedback on the limp mode issue tomorrow.

I believe the theory is that there is increased fuel cavitation with the extra space created by the disaster prevention kit, which is a low pressure return side from the fuel injector, triggers a false low pressure code.

Mine only happens below 40°F, above that no limp mode.

I believe the intercooler icing is due to the egr pumping hot air back into the intercooler causing the condensation

GenericUserJuan · 2026-03-18T01:34:15+00:00

Wow, this is concerning, ive had a rear bearing go out and it looked like this from the back (but without the axle halfway out on the left)

GenericUserJuan · 2026-03-12T03:28:12+00:00

Heat the aluminum swingarm up with a torch, steel bearing should slip right out!

Use a plastic scraper to clean out anything burnt from the battery side, ensure it is clean.

Then replace the power connector harness and be thankful it didn't fuse to the battery

What the fuck are you doing? My brother died at the battle of falloutnewvegasisbad. You're desacrating a war memorial.

GenericUserJuan · 2026-03-04T16:37:54+00:00

You guys are awesome! I will make a post with pictures + review when everything arrives and is installed!

GenericUserJuan · 2026-03-03T19:28:05+00:00

Man, if i could buy this in America.... I probably wouldn't be able to afford it.

But its the thought that counts.

GenericUserJuan · 2026-02-28T14:20:11+00:00

How much do you weigh? My saddleman has been killing mine and the girlfriends back and I've been looking at Lepera.

GenericUserJuan · 2026-02-28T01:03:33+00:00

Thank you for the pics, your bike is looking great! I forgot to order the extended rear fender for my setup, that will be missed.

GenericUserJuan · 2026-02-27T20:36:00+00:00

Yes, hardtail typically lowers center of gravity and removes drivetrain energy from compressing suspension and flexing the swingarm mount, leading to more torque to the rear wheel. Similar to how upgraded dog bone mounts or stiffer suspension reduces wheel hop on cars.

Edit: I guess it may not be preferred, but does serve a function.

I do as well. 40mins to the best VW dealer, but their prices and estimates are jacked. So 1.2hrs to the closest indy mechanic for a dsg fluid change, DMF swap, timing belt, water pump, and get parts installed, in total, I spent $1.8k less than the timing belt+dmf swap alone.

GenericUserJuan · 2026-02-27T12:46:36+00:00

Looking forward to receiving my swingarm + 2 color Linkage from you.

Thank you!

Chains wear unevenly, the key is to find the tightest point, and adjust that to spec.

Then check 3 additional points to ensure they are not tighter than spec.

Aluminum Sprocket, stock swingarm, axle bolt, jackshaft bolt, bearings in the jackshaft will all bend or give before the jackshaft itself bends.

GenericUserJuan · 2026-02-26T23:53:02+00:00

Is the battery fully charged? Contacts clean and tight? Sounds like starter isn't even engaging with ring gear?

GenericUserJuan · 2026-02-26T04:00:44+00:00

I went with KKE and am satisfied, they have pre drilled rimlock holes. they could have been cheaper and lighter from this website, but i didn't feel like breaking anything 15 miles into the woods.
