Stock s-40 uses a 94mm piston. Wiseco makes 95mm, 96mm, and a 97mm piston. 96mm piston with stock 94 mm stroke gives 680cc. The piston with shipping costs about 230dollars. The price of cylinder boring is just over a hundred dollars at a dependable shop. Then there is the cost of gaskets and labor unless you do your own. Google Wiseco pistons for details |

Better check that again, or better yet call/e-mail them as I did. Thats a No Go on any piston for the LS650 street bike. |

It's especially not a good sign when they do list the LS650 as a dirt bike. |

Well they list it under the dirtbikes, and the person who e-mailed me back said no they dont carry that. May be wrong but I sure cant find it. Got any pics ? I'd like to get my hands on a Forged piston with a slightly raised top and valve cutouts.... We can get some custom pistons if we can get 4 or more people wanting them from ROSS Pistons, they only make custom slugs in 4's... Get them in the same dia as that of Chevy 305 V8's and we can use the Gapless Ring sets !!! |

Title: Re: boring out the 650 Post by LANCER on 05/15/09 at 08:21:57 Yep, Wiseco does have them but as stated you do have to look them up under the '90-'95 DR650; and the sizes are 95, 96 and 97mm. Someone on ebay also has a few of them in assorted sizes. |

When you look under dirt bikes in the Wisco site, You find the pistons fo the 96 and earlier DR 650s. Then if you look closely, you will see that they are also for the LS 650. I called on the phone and it was verified. I also asked about how thin the cylinder liner could be bored. They said even down in the skirt area,(the part that extends down in to the block), do not have less than .080" thickness. My skirt area measured 101mm on the outside. If I bored for a 96mm piston that would leave 5mm difference. Divide that by two and get 2and 1/2 mm thickness. That is as thin as I wanted to go so I bought the 96mm piston and merely wished for the 97. Be advised. the piston and wrist pin together in the stock engine weighs 33 grams more than the Wisco piston and wrist pin. You can either put up with a slight imbalance and the vibration it induces, or add weight to the wrist pin to match the original weight. I did the latter. BTW the Wisco piston has a raised crown that in addityion will give an increase in compression. Use the better grade of gas with this piston. Phelonius |

Title: Re: boring out the 650 Post by Phelonius on 05/17/09 at 12:08:52 Okay I found the box it came in. Wiseco piston 4597M09600 Suzuki DR/SP/LS600-650 Mine has been hopping up and down inside my engine for more than 700 miles now so if they don't make one, I have a problem. Phelonius |

It is noticeably quicker through the gears from a stop. Don't know if it added any horses or the ones it got grew a bit bigger. Soon I will try it on a known uphill grade to evaluate. Phelonius |

Title: Re: boring out the 650 Post by LANCER on 05/18/09 at 19:38:44 I've got a couple of spare cylinders sitting on the shelf waiting for something to do .................................................hmmmmmmmmmmmmmmm It would help if I had a lot more spare money though.... wouldn't it be fun to have a kit with a 97mm piston, bored cyl with silicone carbide treatment, and perf. cam/carb combo :D |

It would give about 694cc but it would be getting mighty thin on the lower cylinder sleeve skirt. Try it and tell us how well it works. Phelonius |

Pretty much what Im going for. By the way Lancer. In about a year I'll be sending you the better part of $1K. Stage 1 Cam, Barnett clutch plates/springs, Perf Carb kit w UFO. Maybe DAJ....I plan on a 95 or 96 boretech carbide dealy and corresponding wiseco piston. I dont plan on porting or a more open header at this point but probably in the future. In which case, would just going ahead and getting a stage 2 be more cost effective in the long run or do you think id be better off getting a stage 1 for now? At this point I have stock airfilter, stock header, SE slash cut. Stock Carb - 55 w/bleed holes pilot, 3 washers, 155 main (still a bit lean. Could use a 157.5). |
