Parts Rebuilding Services
Nikasil Electroplating 
Now Available from Harper's!

Engine, Transmission and 
Rear Drive Rebuilds

We strive to provide the highest quality at the lowest possible cost when rebuilding any part of your Moto Guzzi. We feel that our customers satisfaction is more important than a "Quick Buck". We offer good, common sense advise and straight talk about Guzzi repairs. From minor repairs to complete restorations, our service is always the best.

Big Bore Kits
These kits increase the torque, not the speed. They make pulling a trailer or side car much easier. Available for Eldorado, T, T/3 and LM I. Call us for more details. In the USA and 
parts of  Canada call 1-800-752-9735. Outside the USA call 1-816-697-3411. NOTE: Each kit is done as ordered. Please allow 3-4 weeks.

Starter and Generator Rebuilding
When your starter or generator goes on the fritz it can be an expensive experience if you don't know where to go. Our people are specialists in Bosch and Magnetti Marelli repairs and rebuilds.

Quality repairs at the lowest possible cost is our objective. Usually a starter or generator can be repaired inexpensively if the armature or field coils are not burnt or the item has not been damaged by external forces.

Repair costs vary from unit to unit, but generally if the repair costs exceed $150.00, we will stop and contact you for authorization to proceed. This amount is usually the most charged unless the armature, field coils or solenoid have to be replaced.

The new Valeo starter will work on the Eldorado and all Bosh systems. Will not work on Marelli systems. New Valeo starter without exchange is $295.00. Freight will be added at time of shipment.

Nikasil Electroplating 
Now Available from Harper's!
Better than Relining.

Moisture will collect under the chrome inside the cylinder on a Moto Guzzi that has set for a long period of time. this will cause the chrome on the cylinder to blister and peel.
Why have your cylinders Nikasiled? You get much better results than with the steel sleeves. Nikasil dissipates heat much more efficiently than steel. The cylinder walls are treated with the special Nikasil electroplating. Nikasil coated cylinders have a hardend surface that cannot peel and is more wear resistant than the steel sleeves.

Although the Nikasil process is expensive, the resulting increase in the cylinders life span, performance and reliability more than offset the cost.

We will bore the cylinders to fit your pistons or to new pistons.
Note: This process uses the same rings and pistons as OEM cylinders. No special parts needed.  Turn around time about 14 to 21 days.

Testimonial: I would like to compliment Jason, your service manager, on a job well done. I brought my SP III over from Leavenworth and not only did Jason do a superb job syncing my carbs, but took the time to look at something small, but quite significant...little metal particles on the ignition magnetic pickup. I know that I am in good hands when I take it to Jason.   Cordially, Rich Clapsaddle.
