Advice on a monster 620

[sbrguy]

with a bike with about 8-10k miles on it without a service and you are getting close to 18k miles total, this bike will probably need at the least. bc most of it has to be done anyway for th 18k service.

valve clearances checked and fixed
new belts installed
new oil/filter and probably clean out metal oil filter, others know what this is.
if its 8k miles on the tires, then you proably want/need new tires
if its 8k-10k miles since last main service you probably need a new chain and sprockets i went through them in 12k miles and a second chain in 7k miles
if its the original battery you would proably want to replace that, 4 years is basically the life of a motorcycle battery.
check forks see if there is any problems.
change brake/clutch fluid and possibly need new rear brakes at least

all of this if you bring it to a good 3rd party mechanic will probably cost around 1k-1.1k dollars only bc the tires/chain and battery will cost you even if you bought it from the internet and had him with just labor install them for around $400 total= 250 tires/100 battery/100 chain and this is somewhat conservative you might find better deals. that leaves around 600-700 for the normal service which is probably what a dealwer will charge you.

so what you could do if you really like the bike is tell the guy this and see if he will come down by 500-1000 doubt he will do it but its something to ask.

You should have it looked at first by an authorized dealer before any decision is made. A full service will cost you up to $800 given the obvious neglect. But then too, that bike is a Monster. Its a well built machine, that will last if you take care of it.
