If you are interested in purchasing one, there are a few known issues to be aware of. The V-twin engine can be sensitive to timing since there are two moving pistons and two sets of valves. There can be issues with the timing chain tensioner allowing too much slack in the chain and allowing the timing to be off.
Under this condition, the engine will not start until the timing chain is repositioned and a new tensioner installed. Ignition, or spark, issues can be related to timing issues.
Likewise, timing chain issues can cause symptoms similar to no spark issues. However, issues with spark require diagnosing different components of the engine, namely the spark plugs, wires, and ignition coils. There can be several different reasons why an engine would have issues starting. One common issue is having a bad battery. Batteries can degrade over time and especially take a hit when improperly stored. Likewise, if there is an issue with a short circuit constantly draining the battery, the life of the battery will be shortened drastically.
Along with engine operation, there is some discussion about the jets in the carburetors backing out. This can be tricky to diagnose without disassembling the carb. Symptoms of this issue include lack of power at speed and poor starting and idling.
The carburetors can get out of sync due to road and engine vibrations gradually loosening adjuster screws. Symptoms include poor idling and low-end power. Clutch wear is to be expected over the life of the motorcycle and clutch slippage is fairly common. Symptoms include poor acceleration in lower gears. The clutch is also sensitive to using the right transmission oil.
Aside from these issues, another aspect to take note of is the fact that these motorcycles have a driveshaft in place of a chain. A drive shaft should be fairly reliable, but issues can arise with u-joints and the final drive gears.
Diagnosing requires verifying that each component is functional, which can be tedious and time-consuming, and requires some mechanical know-how. Having a reliable source for information is critical to making repairs. Online forums are a decent way to learn, but it can be difficult to communicate specific issues. A solid source of information is a Yamaha manual for the XVS, which is available to purchase online. You can find manuals at emanualonline.
Concerning the timing chain tensioner, this will be a pretty involved repair for someone with minimal mechanic experience. While it is possible to do at home, extra caution should be taken when taking the engine apart. Typically, the tensioner wearing out should prevent the chain from wearing out, so only replacing the tensioner is common. However, this is a case-by-case issue and discretion should be used.
When diagnosing ignition issues, it is safe to start at the spark plugs. You must be logged in to post a comment. News Ticker. About Michael Le Pard Articles. Owner and Founder of Total Motorcycle.
