83400maxim Posted December 10, 2008 Share Posted December 10, 2008 Well last year I bought an 83 maxim 400 DOHC with about 4500 miles on it.. Now it has 8000... I'm just wondering what the valve check intervals are on these bikes? How often do they need checked and how hard are they to check? Also, if out of spec how hard are they to adjust on this bike? Its winter so I do have some spare time and can't ride anyways but I dont want to mess with it if it isnt necessary. Thanks! Link to comment Share on other sites More sharing options...

I found a manual for an 82' seca.... would that be the same engine as an 83' maxim? and it lists the intervals as every 2000 miles (assuming its the same engine)..... the job itself doesnt look difficult but every 2k seems excessive and i was hoping for maybe a more realistic interval which people have expeirenced Link to comment Share on other sites More sharing options...

Moderator YamaHead Posted December 11, 2008 Moderator Share Posted December 11, 2008 I rode an '82 Seca400 for 40k miles.......only shimmed the valves once in that time. Link to comment Share on other sites More sharing options...

I actually have an 06' gsxr 750 that I take out when I'm going for more than 50-60 miles though its funny since I picked up the Maxim as a beater bike to run errands and such, its aquired more miles than the 750. I've gotten to used to being able to leave it outside and jump on it everytime I need to go somewhere quick or even for a short ride so Im deciding to fix it up a bit this winter and at least keep it mechanically in good shape. As a side note.... Does anyone else feel a void in the US bike market for bikes in the 400-500 cc range? I understand that the demand in the US is not there for them but personally I feel they are the perfect size for a commuter bike (perhaps a bit weak if the highway is involved) Also I love all the old UJM's .. I prefer to have my feet under me, not 3 feet out in front as all the new cruisers are. Only new bike that catches my eye are the Bonnevilles Link to comment Share on other sites More sharing options...

Only new bike that catches my eye are the Bonnevilles No, you're not the only one. 250cc is too small for comfortably going 60mph, and 600+cc gets heavy in town and uses a lot of gas. 350-400cc bikes are perfect for 55-65mph travel as well as in town, are relatively light weight and use very little gas (between 55-75mpg normally). But for some reason you can't buy them (new) in the US anymore. I wish you could. Link to comment Share on other sites More sharing options...
83400maxim Posted December 22, 2008 Author Share Posted December 22, 2008 Well... got the valves checked today.. overall not bad at all.. all were within spec and over half the time was spent trying to get the old gasket off the valve cover... apparently it was glued on and was a major PITA to get off. Guess now all thats left is to wait for summer to come again.... Link to comment Share on other sites More sharing options...
