We all our favorites: our 1987 Suzuki has been with me since childhood. From the cabin, to the farm, to plowing snow, to pulling trailers, to super-low diff lock its arguably the most reliable and best ATV ever made. No chains. No belts. Well loved.
A goal is to make this a resource to keep these machines alive. More to come with specific tips, facts, and information specific to the:
LT-4WD 1987-1998 Suzuki QuadRunner 250
LT-F250F 1999-2002 Suzuki QuadRunner 250 – newer body style
LT-F4WDX 1991-1998 Suzuki King Quad 300 [300cc]
LT-F300F 1999-2002 Suzuki King Quad 300 [300cc] – newer body style
“Tackle the tough terrain in four-wheel drive, or switch easily to two-wheel drive using the dash mounted lever and discover what it can really do. The front differential can even be locked when in super low range for extra traction on snow, mud and ice.”
Suzuki lived up to the ads. I purchased NOS brochures and the official Suzuki Service Manual off eBay a few years ago and scanned them in an attempt to preserve history. The ad at the top was the first year: 1987 model pictures. Square axle nut boots (cone shaped all other years ), silver skid plate up front (black all other years), and the only year with the flip up/down front and rear racks. The LT-4WD had a retail price of $3298.00.
Its been too long. Small engines are a personal hobby; something I can do with our kids and my father. And its an opportunity to learn from “old” technology. I sincerely enjoy understanding the designs of the past; especially when we can’t implement the simplicity today (e.g. due to emissions).
My father picked this up. A first year, all original, one-owner 1971 Suzuki MT50 Trail-Hopper. Has 2665 miles on it. Included is an old Suzuki ad for this fun little machine (courtesy of CollectorsWeekly).
In the process of getting it back running, I could not locate a Service Manual for the MT50 that was freely available. Its important to pay it forward. Here is a scanned copy of a complete Suzuki Service Manual & Part List for Suzuki MT50 TrailHopper 1971, 1972, & 1973. The best section? Reed valves and C.C.I. pages 103-108.
May we take this opportunity to express our appreciation for your continuous efforts in expanding the sales market for our products. At this time we have marketed the Suzuki MT50, which has been made completely new in style and excellent in performance. The Suzuki MT50 has outstanding mechanisms such as reed valve, Suzuki "C.C.I." system and automatic clutch. The engine performance has been improved especially in low speed and climbing ability. And also its top speed registers 48-56 k m/h (30-35 mph). This Service Manual explains, mainly, the principles and construction of these new mechanisms. The most important items, such as disassembling, assembling, tips on adjusting, maintenance standards and tips on handling, are briefly but clearly described in this Manual. By making a practice of using this Manual, it will assist you in performing perfect servicing.
